All my extensions have disappeared

Using Opera developer 56.0.3023.0 on Windows 7 Home x64 yesterday I closed Opera normally and went to sleep and today after waking up I noticed all of them are gone. I thought they just disabled themselves (happens sometimes) but they are not present in the extensions at all. It's like all of them were uninstalled. The profile is OK (my bookmarks are there) but I'm afraid there are no extension folders in the AppData. Is there any way to get them back?

EDIT: I can restore previous version of my "Extensions" folder dated back to two days ago (seems like it containt my extensions) but it does not help. Nothing changes, when I load them manually, it's also nothing http://i.imgur.com/Zl2gXIm.png

What is this crap... i want my old Opera browser and extensions back... is there a way to roll back? I use the extension "Notebook" daily, and the screen clipper... you have just ruined the reason I loved this browser
